Granted: 2003-02-27
Abstract: This invention describes a novel agent for the targeted control of a mammalian cell activity, in particular the agent is used to control the interaction of particular cell types with their external environment. The agent has applications as a pharmaceutical for the treatment of a variety of disorders. An agent according to the invention comprises three Domains B, T and E linked together in the following manner: Domain B-Domain T-Domain E where Domain B is the Binding Domain which binds the agent to a Binding Site on the cell which undergoes endocytosis to produce an endosome, Domain T is the Translation Domain which translocates the agent (with or without the Binding Site) from within the endosome across the endosomal membrane into the cytosol of the cell, Domain E is the Effector Domain which inhibits the ability of the Recyclable Membrane Vesicles to transport the Integral Membrane Proteins to the surface of the cell.

Abstract: (1) Abstract The invention relates to a chair, in particular a work or office chair, having a seat that is pivotable toward the front about a horizontal pivot axis and is variable in inclination and having a backrest that is compulsorily variable in inclination overproportionately as a function of the change in inclination of the seat, wherein with increasing inclination of the seat the backrest executes an additional relative motion with respect to the end toward it of the seat, wherein pivot levers are articulated to support arms of the chair frame on both sides of the seat, the free ends of the pivot levers being attached fixedly and nonrotatably to the backrest and support it, and wherein the seat is rotatably connected to the pivot levers approximately in its middle region.  The desired relative motions between the seat, seat back and chair frame can be accomplished and varied solely by means of the coupling between the seat, the backrest, pivot levers embodied as arm supports or armrests, and the chair frame, in that the seat, in the region of its front edge, is supported shifted upward with respect to the pivot shaft of the pivot levers, being nonadjustably or limitedly adjustably (2) rotatable on extensions of the support arms, and that the axis of rotation between the pivot levers and the seat is limitedly adjustable or nonadjustable.

Title: Transmission control for self-propelled implement (13540-can)
Inventor: SCHWEITZ KENNETH D
IPC: A01D34/68
Filed: 1990-01-26
Granted: 1993-05-25
Abstract: TRANSMISSION CONTROL FOR SELF-PROPELLED IMPLEMENT Abstract of the Disclosure A drive wheel control for a walk-behind self-propelled implement, such as a lawn mower.  The control activates seguentially a transmission ball clutch and then a V-belt drive to provide positive and gradual drive wheel start up. Disengagement of the ball clutch allows the drive wheels to freewheel and permits the operator to easily move the mower backwardly as when trimming around hedges and bushes.  The control includes a pair of links pivotally connected, with one link rigidly mounted to the transmission.  Movement of a single control cable connected to one link initially activates the ball clutch and then causes rocking movement of the other link and the transmission to engage the V-belt drive.

Title: Fluid impingement method & apparatus for fruit meat extraction
Inventor: KOCK RONALD W
IPC: A23N1/00
Filed: 1990-02-16
Granted: 1997-08-05
Abstract: Method of and apparatus for extracting whole juice sacs from citrus fruits by fluid impinging chunks of peeled fruit meat. In one embodiment,  a fruit chunk is fed into a fluid impingement chamber  that   includes   a   plurality  of  off-center   orifices. High-pressure fluid emitted from the orifices strikes the fruit chunk and spins it such that the fruit chunk's juice sacs are stripped from the chunk's sectional membranes.  In another preferred embodiment, a plurality of fluid  impingement  chambers  are  incorporated  into  a high-speed,  continuous  motion  turret.   In yet  another  preferred embodiment, fruit chunks are fed into an inclined tube that includes fluid orifices which emit high pressure fluid.  Controlling the fluid pressure, nozzle orifice size, number of orifices, direction of fluid jets,  impingement  time,  and  size  and  shape of the fruit  chunks determine how substantially the radial membranes of fruit chunks are stripped of juice sacs without shredding the membranes.  By avoiding contamination by or commingling with flavor-deteriorating membranes or peel components of fruits,  the resulting juice and juice sac slurry has  a taste more  like  fresh-squeezed juice after  further processing and storage than current commercially-made juice.

Granted: 1999-04-27
Abstract: .alpha.-Glycosyl hesperidin, a novel hesperidin derivative wherein  equimolar  or more  D-glucose  residues  are  bound  to hesperidin via the .alpha.-bond,  is formed by a saccharide-trans-ferring enzyme in a liquid containing hesperidin and .alpha.-glucosyl saccharide.

Title: Coding method and apparatus for pipelined and parallel processing
Inventor: CIDECIYAN ROY DARON
IPC: H03M5/14
Filed: 1991-07-12
Granted: 1996-09-10
Abstract: For encoding a stream of k-bit data bytes into a stream of m-bit code bytes satisfying given constraints, a coding principle and coder apparatus are disclosed which allow pipelined and parallel handling of the byte stream. Each data byte DB and an associated coder state indicator S are together converted into a code byte CB. The coder state indicator S(i) to be associated with a databyte DB(i) is obtained by logically combining the coder state indicator S(i-1) of the preceding data byte DB(i-1) and a state transition indicator T(i-1) derived from the latter. This allows the simultaneous generation of all coder state indicators S for a whole group (a word) of data bytes thereby enabling the parallel and pipelined operation of the coder.

Title: Pulsed pen for use with a digitizer tablet
Inventor: RUSSELL GREGORY F
IPC: G06F3/033
Filed: 1992-03-02
Granted: 1996-01-16
Abstract: An inductive pen (16) repetitively transmits pulses of an oscillatory signal having a characterisitic  frequency. Pen state information,  such as pen tip contact switch information, are encoded by a number of techniques. These techniques  include  pulse  width  modulation  or  pulse position  modulation,   so  as  to  convey  pen  state information to a digitizing tablet in a manner that does not adversely affect pen position determinations. The pen state information may also be encoded on the oscillating signal  by  Frequency  Shift  Keying  (FSK),  Phase  Shift Keying (PSK), or Amplitude Modulation (AM). A digitizer tablet   (10)   includes  circuitry  for  detecting  the transmitted  pen   state   information,   the   circuitry accommodating the selected modulation scheme. The tablet is  responsive  to  the  transmitted  pulses  for  placing tablet circuitry in a low-power consumption state between pulses so as to conserve tablet power.

Abstract: A unique plastic retainer is disclosed having a pair of axially spaced cylindrical rings. Retainer arms for retaining an upset portion of a tube within a housing bore extend from a rear ring, and a plurality of webs connect the front and rear cylindrical rings of the retainer. When a tube is initially inserted into the housing bore, it contacts an inner periphery of the arms. The retainer then moves axially forwardly within the bore for a small distance until the forward ring abuts s seal package within the housing. Further movement of the retainer is then prevented, and the upset portion of the tube causes the arm to flex radially outwardly at a flex point in the rear ring. The upset portion may then move axially beyond the arms into a fully connected position within the housing.
